Task NameHTTP_Function_Object
DescriptionThis task is more of a building block than a single task. When sending/receiving many HTTP(S) requests within a cloupia script, the code can quickly become hard to read or understand. I've therefore created an HTTP(S) function that is more object oriented.
Prerequisites
  1. Tested on 5.2
CategoryWorkflow
ComponentsIt has a custom task and sample test workflow..
User Inputs

Instructions for Regular Workflow Use:

  1. Download the attached .ZIP file below to your computer. *Remember the location of the saved file on your computer.
  2. Unzip the file on your computer. Should end up with a .WFD file.
  3. Log in to UCS Director as a user that has "system-admin" privileges.
  4. Navigate to "Policies-->Orchestration" and click on "Import".
  5. Click "Browse" and navigate to the location on your computer where the .WFD file resides. Choose the .WFD file and click "Open".
  6. Click "Upload" and then "OK" once the file upload is completed. Then click "Next".
  7. Click the "Select" button next to "Import Workflows". Click the "Check All" button to check all checkboxes and then the "Select" button.
  8. Click "Submit".
  9. A new folder should appear in "Policies-->Orchestration" that contains the imported workflow.

The function allows you to choose between HTTP (Including session persistence) and HTTPS (“Tolerant of self signed certs),  use basicAuth, insert headers and read responses either in string or stream form.

Here’s the actual cloupia script (UCSD 5.2):

//   Description: HTTP Request function - httpRequest.

//

//                I have made the httpClient functionality more object like in order to

//                make cloupia scripts more readable when making many/multiple HTTP/HTTPS

//                requests within a single script.

//

//      Usage: 1. var request = new httpRequest();                  // Create new object.

//               

//             2. request.setup("192.168.10.10","https","admin","cisco123");      // SSL.

//          or:   request.setup("192.168.10.10","http","admin","cisco123");       // HTTP.

//          or:   request.setup("192.168.10.10","https");           // SSL, no basicAuth.

//          or:   request.setup("192.168.10.10","http");            // HTTP, no basicAuth.

//

//             3. request.getRequest("/");                    // HTTP GET (URI).

//          or:   request.postRequest("/","some body text");  // HTTP POST (URI,BodyText).

//          or:   request.deleteRequest("/");                 // HTTP DELETE (URI).

//

//  (optional) 4. request.contentType("json");            // Add Content-Type HTTP header.

//          or:   request.contentType("xml");

//

//  (optional) 5. request.addHeader("X-Cloupia-Request-Key","1234567890");  // Any Header.

//

//             6. var statusCode = request.execute();                     // Send request.

//

//             7. var response = request.getResponse("asString");   // Response as string.

//          or:   var response = request.getResponse("asStream");   // Response as stream.

//

//             8. request.disconnect();                             // Release connection.

//

//

//          Note: Be sure to add these lines to the top of your script:

Has anyone had success or can point me in the right direction with this :  Successfully post with this (to vCo in this case) and kick off flows over there, but when I to a get to bring back the results the body only gets about half the data. Its the same as a stream or as a string. Its a constant 1010 bytes. Its almost like its hitting a buffer limit somewhere.  Without the complete json reply I cant dig out the data I need. 

If use another rest client I do get the entire body. Its very strange.

I cant find any mention of getResponseBodyAsString() having any limitations like that.

Any advice appreciated.

Thanks.
